Stormy Daniels says she was approached by a man and told to "forget the story"

A porn star who claims she had an affair with Donald Trump in 2006 says she was threatened to stay silent.

The US President has repeatedly denied the alleged affair.

Stormy Daniels - whose real name is Stephanie Clifford - has told CBS News' 60 Minutes she was approached by a man in a car park in 2011.

She told interviewer Anderson Cooper: "I was in a parking lot, going to a fitness class with my infant daughter. Taking, you know, the seats facing backwards in the backseat, diaper bag, you know, gettin' all the stuff out.

"A guy walked up on me and said to me, 'Leave Trump alone. Forget the story.' And then he leaned around and looked at my daughter and said, 'That's a beautiful little girl. It'd be a shame if something happened to her mom.' And then he was gone."

She said she has never seen the man since, but added she was left 'rattled' by the alleged encounter.

Ms Clifford is currently looking to be released from a $130,000 (€105,000) non-disclosure agreement about the alleged affair she signed before the presidential election in 2016.
